Ansible与VMWare一起使用Ansible创建字典

Question

我正在尝试为VMWare详细信息集合创建一个包含项目列表的字典。我能够单独创建列表。但不确定如何合并。

- name: Gather DC info
community.vmware.vmware_datacenter_info:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
validate_certs: false
register: datacenter_infor
- name: Set DC_name variable
set_fact:
# dc_name: "{{ item.name }}"
dc_name: >-
{{ (dc_name | default([]))
+ [item.name]
}}
loop: "{{ datacenter_infor.datacenter_info }}"
- name: Gather cluster info
vmware_cluster_info:
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_username }}"
password: "{{ vcenter_password }}"
validate_certs: false
datacenter: "{{ item }}"
register: cluster_info
loop: "{{ dc_name }}"
- name: Set Host_name variable
set_fact:
host_name_list: >-
{{ (host_name_list | default([]))
+ data
}}
vars:
data: "{{ item.clusters.values() }}"
loop: "{{ cluster_info.results }}"

这将导致以下输出：

TASK [Set Host_name variable] *********************************************************************************************************************************************************************************************
ok: [localhost] => (item={'changed': False, 'clusters': {'PQR-CLU01': {'hosts': [{'name': 'PQR-cn0001.myhost.com', 'folder': '/PQR/host/PQR-CLU01'}, {'name': 'PQR-cn0002.myhost.com', 'folder': '/PQR/host/PQR-CLU01'}})
ok: [localhost] => (item={'changed': False, 'clusters': {'ABC-CLU01': {'hosts': [{'name': 'ABC-cn0002.myhost.com', 'folder': '/ABC/host/ABC-CLU01'}, {'name': 'ABC-cn0001.myhost.com', 'folder': '/ABC/host/ABC-CLU01'}})     

我如何创建一个包含以上项目的词典，如使用ansible:

{'PQR-CLU01': ['PQR-cn0001.myhost.com','PQR-cn0002.myhost.com'],'ABC-CLU01':['ABC-cn0002.myhost.com','ABC-cn0001.myhost.com']

Answer 1

给定数据

cluster_info:
results:
- changed: false
clusters:
PQR-CLU01:
hosts:
- folder: /PQR/host/PQR-CLU01
name: PQR-cn0001.myhost.com
- folder: /PQR/host/PQR-CLU01
name: PQR-cn0002.myhost.com
- changed: false
clusters:
ABC-CLU01:
hosts:
- folder: /ABC/host/ABC-CLU01
name: ABC-cn0002.myhost.com
- folder: /ABC/host/ABC-CLU01
name: ABC-cn0001.myhost.com

Q:"；创建字典(如下(">

cluster_dict:
ABC-CLU01:
- ABC-cn0002.myhost.com
- ABC-cn0001.myhost.com
PQR-CLU01:
- PQR-cn0001.myhost.com
- PQR-cn0002.myhost.com

A： 创建集群列表

cluster_list: "{{ cluster_info.results|
map(attribute='clusters')|
map('dict2items')|
flatten }}"

给出

cluster_list:
- key: PQR-CLU01
value:
hosts:
- folder: /PQR/host/PQR-CLU01
name: PQR-cn0001.myhost.com
- folder: /PQR/host/PQR-CLU01
name: PQR-cn0002.myhost.com
- key: ABC-CLU01
value:
hosts:
- folder: /ABC/host/ABC-CLU01
name: ABC-cn0002.myhost.com
- folder: /ABC/host/ABC-CLU01
name: ABC-cn0001.myhost.com

创建密钥列表

cluster_keys: "{{ cluster_list|
map(attribute='key')|
list }}"

给出

cluster_keys:
- PQR-CLU01
- ABC-CLU01

创建值列表

cluster_vals: "{{ cluster_list|
map(attribute='value.hosts')|
map('map', attribute='name')|
list }}"

给出

cluster_vals:
- - PQR-cn0001.myhost.com
- PQR-cn0002.myhost.com
- - ABC-cn0002.myhost.com
- ABC-cn0001.myhost.com

把字典装进

cluster_dict: "{{ dict(cluster_keys|zip(cluster_vals)) }}"

给出

cluster_dict:
ABC-CLU01:
- ABC-cn0002.myhost.com
- ABC-cn0001.myhost.com
PQR-CLU01:
- PQR-cn0001.myhost.com
- PQR-cn0002.myhost.com
